-- ALLEGANY, rENNsYLvANI' I MoTIoN-ooNmRoL MEANS FOR THE SPINDLES on TEXTILE SPINNING MAoH INEs Application filed August 14, 1928, Serial No. 239,618. Renewed May 26, 195 30.

The present invention relates to textile spinning machines and hasfor its principal object to provide means for controlling the spindle for the bobbin so that the bobbin may be renewed, when desired, without interfering with the continuousoperation' of the machine. v p

An important object of the invention is to provide a friction drive ineansfor theispin-I dle and a friction brake therefor, both being controlled through the operation of a single control lever and arranged for opposite actuation upon the operation of the lever. Another important object'is to provide a friction disk clutch forming an operative connection between the spindle and a driven shaft and a friction disk'b'rake for the spindle andfarranging the clutchand'brake for control through a single control lever Whereby to reverse the'positionfromthe operation of the lever.

Another important object of the invention is to provide a motion control device for spindles of this character permitting a positive drive connection between the driven shaft of each of the spindles and the drive shaft of the spinning machineiwhereby to prevent the possibility of slippage occurring between said shaft and thus provide for the uniform operation of the spindles'of the machine.

An additional object is to provide a motion control device of this character of a simple andpractical construction, which is strong and durable, efficient-and reliable in performance, which may be installed in operativeposition upon the spinning machine without necessitating any material changes or alterations in the construction thereof, which is relatively inexpensive to manufacture and install and otherwise well adapted for the purposes for which the same is intended.

'Other objects and advantages reside in the special construction, combination and arrangement of the variouselements forming the invention as more fully hereinafter de scribed and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein like numerals refer to like 7 parts throughout,and in whichi Figure 1 is a vertical sectional view through a spindle mounting embodying the motion controlmeans constituting the sub ectmatter of our invention, 7 I Y F igure 2 ,'s a transverse sectional View taken substantiallyalong the line 22 of 5 Figurel, e v I Figure 3 is a side elevationalview of the driven shaft for thespindle and i 1 Y Figure 4 is a fragmentary side elevational view, withparts broken away, and shownin sect on, of the friction clutch providing the. drive connection between the drivenf'shaft and the spindle. V J x 5 v Referring to the drawings in detail, where. 1n for the purpose of illustration weighave dlscloseda spindle assemblyifor spinning machines, it being understood that the machine may be provided with any desired num ber of the spindles, all being operated through a common drive shaft indicated at 5. At spaced intervals upon the-shaft fi, adjacent each ofthe spindles is arranged a worm Wheel 6 operatively engaged witha worm 7 formed on a vertically disposed tubular driven shaft 8. The upper portion of the. shaft is formed with a disk or angular plate member 9, cast integrally with the shaft, as niay'also the wormi, i

The lower'end of the shaft is externally threaded as shown at 10 and the entire shaft is closed Within a suitable housing 11. The housing is fixedly mounted to a stationary part of the machine 12 by capscrews 13 or the like. I

Theportion of the housingdisposed immediately below the disk ,9 is formed with an inturned flange 14; providing asupport for a bearing assembly 15 interposed between the flange andthe disk 9, The inner portion of the housing adjacent the lower end of the shaft 8 is, formed with an inner shoulder 16 providing a seat for a bearingassembly-17 for the lower end of the shaft and secured in adjusted position'bya nut 18v threaded on the threaded end 10 of the shaft. V i i 'The shaft 8 is thus mounted for rotation within the housing and operated througha direct drive connection by means of the gear and'worm 6 and 7 respectively. A spindle 19 is supported. on the disk 9 by means of .a

collar formed intermediate the ends of the spindle, the portion of the spindle beneath the collar constituting a shank 21 extending through the tubular shaft 8.

The lower end of the shank 21 protrudes beneath the lower end of the shaft 8 and is externally threaded as shown at 22. A friction disk 23 is interposed between the disk 9 and collar 20, said disk being constructed of suitable friction gripping material where 'by to'trans'mitthe rotation motion of the shaft to the spindle when the collar of the dles seate up n th k i enga ment therewith.

The lower. end of the housing 11 terminates in a tubular extension 24 with its lower edge protruding slightly below the lower end of the shaft'8 and disposed for engagement with the lower edge of the extension is a friction disk 25 carried at the lower end ofthe shank 2-1 of the spindle by a nut 26 threadedly engaged on the threadedportion 22 of the shank.

The nut 26 is secured in longitudinal adjusted position upon the shank by means of a jam nut 27' whereby to secure the disk 25 in adjustable spaced relationwith the lower edge of the extension 24 and arranged disengaged therefrom when the collar 20 of the spindleis in engagement with the friction disk 23. i 1

Disposed about the lower threaded end of the shank 21 is a coil spring 28 having its upper end abutting the stationary part of the machine 12 and its lower end engaged by a washer 29 freely carried at the lower end' of the shank 21.

The lower face of the washer 29 is formed with an annular recess in which is seated a bearing assembly 30 retained in positionin the under side of the washer by a nut 31 threaded on the lower threaded end of the shank, said nut having its outer surface formed into a head 32 forming a cover for the extreme lower end of the spindle.

' Disposed for engagement with the head 32 is a bell crank lever '33, which maybe attached to the machine for operation inany suitable manner by the operator thereof, as for instance by the foot of the operator whereby to efiect an upward movement of the spindle 19 u on the action of said lever.

It will be apparent from the foregoing and from a careful inspection of Figure 1 of the drawings, that the springv 28 will normally retain the spindles in a downward position so that the same will be rotated by reason of the engagement of the collar 20 with the friction 23 which forms substantially the friction disk clutch for operatively con necting the, spindle with the disk 9 of the i vee's ia t. I

7 positive drive connection is thus proiQ Qf the spindle through tll gears 6 and Z for operating the spindle a manner well known to the art. Whenever it is desired to throw the spindle out of operation, as'for instance, for the purpose of renewing the bobbin, the lever 35 is actuated whereupon the bobbin is moved upwardly through the tubular driven shaft which movement simultaneously effects a disengagement of the collar 20 with the disk 23 and also resuits in an engagement of the stationary angular extension 2 1 of the housing with, the friction disk 25 to produce a braking action for the spindle.

T e sp n le may hus be. 1 h ld agai s movement while the bobbin is changed and withoutinterfering with the continued rotation of the driven shaft 8.

' As soon as the lever 33 is released the spring 28 will operate to return'the spindle to its downward position whereby to release the brake and permit the engagement of the collar 20 with the disk 23.

It will be appreciated that only a slight vertical movement of the spindle is necessary to throw the same into. an out'of operative engagement with the driven shaft 8, the extent of such movement to accomplish this result indicated by the dotted lines in Figure 1 of the drawings.

An adjustment for the clutch device is provided by .means of the nut 31 for controlling the tension ofthe spring 28.
